Did you know that Prague’s largest body of water is right here? Welcome to the Hostivař Reservoir a hidden gem on the southeastern edge of the city.
The Hostivař Reservoir isn’t just a pretty face. It’s a vital part of Prague’s flood defense system. Constructed between 1961 and 1963 it holds an impressive 1 845 000 cubic meters of water. That’s a lot of water. More importantly it protects the city from devastating floods. Its creation involved a massive undertaking. Imagine the sheer effort of building a dam 110 meters long and 16 meters high. This wasn’t some small project. This is a testament to human ingenuity.
Beyond its protective role the Hostivař Reservoir is a recreational haven. Its 42-hectare surface is a popular spot for swimming boating and windsurfing. There are grassy and sandy beaches. There’s even a nudist beach for those who prefer a more au naturel experience. Families love it here. Children can play on playgrounds and adults can relax on the spacious banks. The reservoir also supports a thriving ecosystem. It’s a paradise for anglers. Large carp and even sizable catfish weighing up to 50 kg have been caught here.
But the Hostivař Reservoir’s story is more than just its present. It has a rich history. Long before the dam was built the area was home to the Petrovický valley. A mill once stood near the dam. It operated since 1734. Its water wheel was powered by the Botič stream. Earlier attempts at creating a swimming area failed. Floods destroyed simpler structures. Then a more permanent bath was built in 1950. However it was demolished to make way for the reservoir. A significant flood in 1958 finally spurred the construction of the reservoir as we know it today.
In recent years the reservoir has undergone revitalization. This involved dredging the substantial accumulation of sediment. That had been reducing water depth and contributing to algal blooms. The project improved the water quality. It also enhanced the reservoir’s ecological features. New islands for birds and wetlands for amphibians were created. A new wooden pier was built adding a touch of elegance to the lakeside.
Today the Hostivař Reservoir is a beloved recreational area. It’s a testament to Prague’s commitment to balancing urban development with nature preservation. It’s a place to relax swim and simply enjoy the beauty of Prague. It’s not just a reservoir. It’s a story of floods and resilience recreation and nature. It’s a crucial part of Prague’s history and its future. So next time you’re in Prague remember this tranquil oasis. Remember the Hostivař Reservoir.
